Nearly Doubling the Throughput of Multiuser MIMO Systems Using Codebook Tailored Limited Feedback Protocol
Gerhard Wunder, Jan Schreck, Peter Jung
We present and analyze a new robust feedback and transmit strategy for multiuser MIMO downlink communication systems, termed Rate Approximation (RA). RA combines the flexibility an…
The Deterministic Sum Capacity of a Multiple Access Channel Interfering with a Point to Point Link
Jörg Bühler, Gerhard Wunder
In this paper, we use the linear deterministic approximation model to study a two user multiple access channel mutually interfering with a point to point link, which represents a b…
Analysis of Alternative Metrics for the PAPR Problem in OFDM Transmission
Gerhard Wunder
The effective PAPR of the transmit signal is the standard metric to capture the effect of nonlinear distortion in OFDM transmission. A common rule of thumb is the log barrier…
On Interference Alignment and the Deterministic Capacity for Cellular Channels with Weak Symmetric Cross Links
J. Buehler, G. Wunder
In this paper, we study the uplink of a cellular system using the linear deterministic approximation model, where there are two users transmitting to a receiver, mutually interferi…
